I can’t speak to the US, but that’s not what’s happening in Canada, generally. I hear the UK public system is having difficulties, too, but idk the details.
There are some places in Canada that are struggling, particularly in remote rural areas, Indigenous or not (but even moreso for Indigenous schools for historical inequity issues that we’re working on meaningfully addressing with national Truth and Reconciliation work.)
Wireless game streaming is another reason to upgrade WiFi. I couldn’t stream anything from my wired desktop to my Steam Deck on WiFi from the ISP-supplied router. I just finished upgrading to a WiFi mesh network partly because of that… but I haven’t tested game streaming yet.
I expect it should do great, though. My Fire Stick used to occasionally buffer even with ~1.5GB/hr content, but I just tried a 1080p remux at 15GB/hr and it worked great.
